Compact solution from Rohde & Schwarz for analyzing WCDMA and GSM networks
Rohde & Schwarz is now offering as many as three updates for its compact coverage measurement system consisting of the Radio Network Analyzer R&S TSMU and the associated R&S ROMES software. This solution has already been tried and tested in WCDMA network measurements. R&S ROMES now also supports network operators in setting up and optimizing HSDPA networks. The software additionally features an automatic neighborhood and handover analyzer. The R&S TSMU-K13 option enhances the R&S TSMU by adding a GSM network scanner for analyzing receive conditions in GSM networks. The GSM network scanner can thus automatically locate interference sources in the event of co-channel or adjacent-channel interference.
HSDPA will be put into operation in many networks this year and allows downloads with data rates in the range of several Mbit/s per user. Network operators must ensure complete availability of services by skillfully planning their networks; they also decide which parts of the network should first be upgraded with HSDPA. Equipped with the R&S ROMES software, coverage measurement systems from Rohde & Schwarz provide valuable support in setting up HSDPA networks and optimizing radio networks: An end-to-end application is set up and evaluated during a test drive. The measurements supply information about the actual HSDPA configuration, the availability and parameterization of HSDPA services at different locations within the network, the signaling and the data rates achieved at different levels.
When it comes to measurement data acquisition for optimizing WCDMA networks, the R&S TSMU has already set standards as a PN scanner. Equipped with the new R&S TSMU-K13 GSM network scanner option, the R&S TSMU can now also analyze receive conditions in GSM networks. To do so, the R&S TSMU identifies the base stations in the network, measures their power and decodes the sys type information of the individual channels, e.g. CI/LAC/MNC/MCC. Base stations cause interference in GSM networks when transmitting on the same or adjacent channels. Equipped with a GSM network scanner, the R&S TSMU can automatically detect, analyze and display this co-channel and adjacent-channel interference during a test drive. By matching data with the base station list, the interfering base station is clearly identified. The R&S ROMES measurement software includes the application for the GSM network scanner.
In addition, R&S ROMES features an automatic neighborhood and handover analyzer, allowing network operators to check handovers within a 3G network and between 2G and 3G networks online during the measurement. The analyzer automatically compares the measurement results from a UMTS PN scanner, a GSM network scanner and a test mobile phone with the GSM BTS list and the UMTS Node B list. A specially set algorithm tests the system to determine if potential interference is present or if adjacent cells are missing. This convenient solution makes further analysis superfluous.
Combined with the R&S ROMES software, the Radio Network Analyzer R&S TSMU provides a robust compact solution, consisting of a GSM network scanner (all GSM bands), a UMTS PN scanner (bands I to VI) for multiband measurements in up to 12 bands simultaneously plus CW measurement capabilities (80 MHz to 3 GHz). The R&S TSMU can thus determine all the data of WCDMA and GSM mobile radio networks in all bands.
The new functions for the R&S TSMU base unit and the R&S ROMES measurement software are now available from Rohde & Schwarz.
